Gravity..!

Introduction

Hello. The time has come to learn about gravity - one of the weirdest forces in the universe. By watching fun videos and answering short answers you will quickly learn crucial information to understand how gravity and mass works ( An insight ). Here's what some people think about the topic.

Task

By watching these videos you should think about the subject on how you understand it because all of these explanations are only theories, based on some experiments. If you have questions feel free to search the world wide web or re-watch the videos. In this task you are going to watch a few videos and answer a few questions about them to keep some facts in your head about gravity. Hopefully you will learn something new. Good luck!

2. What causes a bigger distortion? 

 

3. What creates gravitational waves?

 

4. Why does light show an exact precision?

 

5. What makes an object fall to the earth?

 

6. What makes the rock fall faster than the feather?

 

7. Why did the two objects fall down at the same time in the bottle?

 

8. Who was the first to explain why lighter bodies fall slower?

 

9. Who made the experiment to prove Galileo was right?

 

10. Is mass and weight the same thing?

 

11. What is weight?

 

12. Which planet has the strongest force of gravity?

 

Evaluation

The correct answers

1. What is a gravitational wave

A ripple in fabric in space and time

2. What causes a bigger distortion? 

Bigger mass

3. What creates gravitational waves?

Mass and or energy 

4. Why does light show an exact precision?

Because with lasers it is possible to see the difference in speed length.

5. What makes an object fall to the earth?

Gravity

6. What makes the rock fall faster than the feather?

The resistance of the air.

7. Why did the two objects fall down at the sa\me time in the bottle?

Because the bottle had no air, it was under vacuum.

8. Who was the first to explain why lighter bodies fall slower?

Galileo

9. Who made the experiment to prove Galileo was right?

Robert Boyle

10. Is mass and weight the same thing?

No

11. What is weight?

Mass x Acceleration of gravity

12. Which planet has the strongest force of gravity?

Jupiter

Conclusion

By watching these videos and answering the questions you now have an insight in gravity! Congratulations!
